Problems solved by technology

[0004] Existing small wind turbines are mostly simple assembled structures, and their blades are generally fixed to the front of the nacelle by bolts. They lack a pitch-changing mechanism and cannot adjust the windward inclination of the blades, so they are not flexible enough to use

Abstract

The invention discloses a pitch varying type small-sized wind driven generator head. The pitch varying type small-sized wind driven generator head comprises a shell, blades, a transmission assembly and a driving assembly, the shell is internally provided with a containing space and externally and fixedly provided with a rotating shaft extending outwards in the axial direction, the blades are evenly distributed on the periphery of the shell in the circumferential direction, the inner end of each blade is fixedly provided with a first bevel gear and inserted into the containing space of the shell, the outer end of each blade outwards extends out of the containing space, the transmission assembly is arranged in the containing space of the shell and comprises a driving shaft extending in the axial direction and a second bevel gear fixed to the driving shaft, the second bevel gear is in meshing transmission with all the first bevel gears at the same time to drive all the blades to rotate soas to change the inclination angles of the blades, and the driving assembly is connected with the driving shaft and can drive the driving shaft to rotate around the axial direction of the driving shaft. According to the pitch varying type small-sized wind driven generator head, the inclination angles of all the blades can be adjusted in a unified mode, the adjusting mode is simple and rapid, andthe stability of the overall structure can be guaranteed after adjustment.

Description

technical field [0001] The invention relates to the technical field of new energy sources, in particular to a variable-pitch small wind power generator head. Background technique [0002] Due to the over-exploitation of traditional energy sources (coal, oil, natural gas, etc.), environmental protection and energy conservation issues have gradually attracted attention. In addition, in recent years, the power industry has been developing towards a higher level from the research of scientific theoretical basis to the practice of engineering technology. Innovation, especially the growing maturity of clean and renewable new energy power generation technologies such as wind power and photovoltaic power generation, has made distributed generation (DG) attract widespread attention. The emergence of DG makes taking electricity locally an important development trend in the future. [0003] Large-scale wind turbines are large in size, difficult to produce and install, and costly (a wi...
